(The stiffness of the beam is small, and no matter how much reinforcement there is, it is useless).

The top plate is 10 pieces, and the thickness of the plate is 12 cm! Now that it's covered, it is recommended that you add a steel column in the middle, which may affect the aesthetics a little, but it is a little safer!

It's hard to judge based on your description alone, because there are many factors related to the safety of the beam. The thickness of the steel bar, the cement number, the sand and gravel and other quality problems, as well as the bearing capacity, the depth of the cracks at both ends, the causes, etc. It is necessary to ask a professional to confirm on site.
